A Brief History of the T Third Part 1: 1860-2007

A Brief History of the T Third Part 1: 1860-2007
By Jeremy Menzies

Earlier this month, we launched free weekend shuttle service in the Central Subway. And come January 7th, our 4 new stations will connect directly to the rest of the T line from Sunnydale to Chinatown. Through this two-part blog series, we will look back at some of the history of the T from the 1860s to today!

In Part One, we’ll look over the first 150 years from the 1860s to the 2000s. Next month in Part Two, we will take a closer look at the history of the T and Central Subway projects leading up to today’s service. 

The Horsecar Era: 1860s-1890s 

Starting in the 1860s, transit service along today’s T Line was provided by horsecars. These were small rail cars (that looked much like a cable car) that were pulled along tracks by horses. Two companies, the Omnibus Railroad and the North Beach & Mission Railway, operated horsecar lines on parts of the path of today’s T. These lines were mainly meant to connect North Beach with the 3rd and 4th street corridors as far south as about Townsend Street.

This photo circa the 1880s shows the busy intersection of Kearny, Geary, 3rd and Market streets, looking south to 3rd.  In the foreground is a horsecar running up Kearny from 3rd. 

Further south on 3rd (then called Kentucky Street), horsecars were operated by the Potrero & Bay View Railroad. Here the route ran over two bridges across Mission Bay and Islais Creek (known as “Longbridge”), ending near today’s 3rd & Gilman. This route served the industrial heart of San Francisco and opened up development in the Bayview but was not very profitable because of its length. 

The Electric Streetcar Era: 1890s-1940s 

The 1890s marked the dawn of the electric streetcar era in San Francisco. A new technology, electric-powered cars could carry more people over longer distances faster than both horse and cable cars. On top of that, they were cheaper to operate and increased profit potential for transit companies.

This 1911 photo shows two cars passing at 3rd (Kentucky) and 20th streets. On the left is a 16 Line car running to its terminal in the Bayview. At right is a 30 Line car heading north to 8th and Market. 

In 1894, the first electric streetcar line began operating along parts of today’s T Line. Known as the 3rd & Kearny Line, it followed much the same route as the early horsecars from North Beach to the Southern Pacific Railroad Depot on Townsend Street. It was extended into the Bayview to 3rd and Palou and eventually was reformed into the 15, 16, and 29 Lines. Each of these served a different portion of the corridor covering differing needs of riders travelling through downtown or all the way out to the Bayview.

Muni’s first streetcar line to serve a similar route to the Central Subway portion of the T was the F Stockton, which opened for the 1915 Panama Pacific Exposition. The F Line ran along 4th and Stockton streets to serve South of Market, Union Square, Chinatown and North Beach before heading out to end at Chestnut and Scott streets. 

Buses along the Bay: 1950s-2000s 

Following World War II, the 3rd Street corridor was among the many that saw transit service shift from streetcars to buses. By 1951, the 15 Kearny route served much of the area once covered by the 15, 16, and 29 streetcar lines.

Traveling along portions of today’s 8 Bayshore and T Third, the 15 route went from Powell and Jefferson streets all the way to Geneva and Mission. Eventually, it was extended to City College on Ocean Avenue. While not the only route to serve the area, the 15 carried the bulk of the load for people wishing to travel along this corridor. 

On Stockton Street, the 30 Stockton bus took over for the F, following the same route through Chinatown, Union Square, and South of Market to 4th and Townsend streets.

Many long-time riders will recognize this view of a 15 bus on 3rd & Palou. Discontinued with the opening of the T Line in 2007, the 15 was revived as the 15 Bayview-Hunter’s Point Express in 2021.  

Tune in next month for a closer look at the history of the T Third and Central Subway Projects.

Show HN: Amazon Seller sent me a postcard asking me to leave a 5-star review Wanted to jump in and throw this here since this is about the first time I've been reached out to by an Amazon seller by mail, directly asking me to leave a 5-star review in exchange for a $20 gift card. With an already struggling E-commerce market, it's quite strange to see the lengths sellers are going to, to buy 5-star reviews from buyers. I am considering reporting this to Amazon, however wanted to run this by you guys and hear similar stories from you! Here is the card I received: https://ift.tt/6M4c5YH https://ift.tt/6M4c5YH November 30, 2022 at 07:07AM

Show HN: SinglePage – Quickly and anonymously publish a page to the web Creating a basic webpage has become way too complicated and expensive. Often there are those times when you just want to share your thoughts with the world but don't want the overhead and complexities that come with maintaining a website. Sometimes, you have an interesting thought piece, an education article, or just a quick and simple bio page that doesn't need the heavy hand of a WordPress blog or Medium post. That's where Single Page comes in. Publish a single page instantly to the web with no fuss. I was laid off three weeks ago from Twitter and I decided to work through a couple of my projects and this was one of them. I've tried blogs over the years, Medium didn't feel right but yet I wanted to quickly post pages online and couldn't find an easy way to do it. So I created it. Feedback appreciated! https://singlepage.cc/ November 30, 2022 at 01:44AM

Show HN: A userscript that adds archive URLs below the paywalled HN submissions https://ift.tt/cuvVSN0

Show HN: A userscript that adds archive URLs below the paywalled HN submissions This userscript adds archive URLs to the metadata section of HN submissions without breaking the immersion. Here are 2 screenshots: https://ift.tt/zRCYFP8 GreasyFork: https://ift.tt/52PFMLY... Source code: https://ift.tt/kM1Am3R Now let me overexplain. -Why?- I never liked paywalled articles. I understand where they come from, but I don't like where we cross our paths. This is why I don't use major news aggregators anymore. Instead, I spend my "catching-up-with-the-world-time" on Hacker News. However, Hacker News (HN) also has its fair-share of paywalled articles. ( Around 11.6% according to my short-lived, half-assed attempt at measuring it. See my super old data https://hpa.emre.ca/ I tell the story below.) -First try- Around a year ago, when I ran the above experiment, my goal wasn't to run that experiment. It was during my self-teaching & career-changing process, I decided to build a React HN clone. To make it stand-out from the bunch, I added a paywall feature. It would detect paywalled articles and would add an archive URL into the metadata. The issue with archiving is unless someone archived the link before on the {archiving-project} then the link is most likely not archived. So me sending people to those projects meant nothing. It kinda meant something for me from an ideological standpoint but I assume you are not me. This rubbed me the wrong way. I decided to build a backend (See https://ift.tt/V0yonvS ) that would scan the links and automatically to detect paywalls close to real-time and submit paywalled ones to archive.is for archival. I used Nodejs, Firebase, and React. I was -still am- really proud because I believed it was doing public good in terms of digital preservation. Only 1 person needed to run this script to benefit everyone. As an extra, I was curious on how many paywalled articles were being shared, by whom, at what time. So I also created some analytics functionality to gather the data. And later created a UI to present it. HN-Paywall-Archiver was great but I stopped running the backend at some point. Because at that point couldn't find a way to continuously run my backend code on some platform for cheap or didn't try hard enough. P.S. Recently I've been thinking of remaking this version with Cloudflare Workers. -Hacker News Paywall Archiver Userscript- After almost a year, I got into userscripts. Super great super awesome concept. People seem to hate javascript unless it is presented as a userscript. So I decided to get my hands dirty to create a simple solution that solves the paywall issue on HN without breaking any hearts. My solution is not perfect as it had to be simple. But here's the rundown. Pros: - Does not beg for attention. - Simple code, simple concept. - Unintentionally, indicates which submissions are paywalled without you interacting with anything. - Not-yet-archived archive links can make you feel like you are contributing to the society after you click on the "archive this URL" button on project page. - Uses HN html defaults, so I hope it plays well with the HN skins/plugins/userscripts you use. Cons: - It doesn't automatically archive the links. - It uses clone of a static list of paywalled websites sourced from a popular Chrome extension. ( https://ift.tt/p1C2gcv... ) So changing the paywall list is slow and manual. - No guarantees of archived links actually having the archive readily available for reading. Though there are currently 3 projects added, so it should be enough for most links. So, there you go. I hope you enjoy it. It can break occasionally due to changes in news.ycombinator code, if you let me know on Twitter, I can fix it ASAP. Otherwise you have to wait until I notice that the script is broken, which can take quite a while as I browse HN on mobile. https://ift.tt/kM1Am3R November 30, 2022 at 04:38AM
